This is an outstanding opportunity to join an innovative and fast-scaling company at the forefront of the quantum computing industry.

Founded in late 2023 and already backed by a specialist quantum investor, the company has grown to 3,000 users and is scaling its Paris HQ team from 9 to 20 over the next 12–18 months. Their platform gives developers a unified Python‑based workspace to build, share, and run quantum solutions across any hardware provider, wrapped in a community layer where algorithms, datasets, and tools are published, reused, and monetised.

This is a rare first‑PM role: you will define the product cadence, rituals, and roadmap for the next 18 months and shape the DNA of a platform that sits at the centre of a once‑in‑a‑generation technology shift

You'll be a strong match if you bring:

• 3–7 years of product management experience, including 2+ years in developer tools, platform products, or technical SaaS.
• Experience building for a community or open‑source ecosystem (this is essential, not optional).
• A technical background, CS degree, prior engineering role, or the ability to read code and discuss architecture.
• Comfort with agile cadence, backlog management, and data‑informed decision‑making.
• Excellent written communication in English.

As the successful Product Owner, you will be responsible for the: 

• Product roadmap & backlog: Turn strategy, user needs, and community signals into clear shipping priorities.
• Specs & user stories: Provide engineering with crisp, unambiguous requirements.
• Community‑centric product design: Incentives, discoverability, reputation systems, feedback loops, designing for creators, not just consumers.
• Product rituals: Sprint planning, reviews, retros, and the metrics that matter (engagement, adoption, execution success, community health).
• Direct user contact: Interviews, usage analysis, and feedback collection, not just dashboards.
• Cross‑functional leadership: Engineering is your closest partner; the community is your north star.

This is one of those rare early‑stage roles where you shape the product and the company’s trajectory.  You work on real engineering challenges with real technical depth.  You join a well‑funded team with a credible path to Series A, and you receive meaningful ESOP at a stage where upside is real.

This role will not be right for Enterprise PMs who’ve never built for a community of creators, project managers without product judgment, or candidates unable to hold their own in technical conversations with senior engineers.

If you are keen to learn more and for a confidential conversation, send your CV across immediately.

  • Community: developers, researchers, open‑source contributors
  • Commercial: enterprise decision‑makers evaluating quantum solutions
• Conference strategy: Q2B, IEEE Quantum Week, APS March Meeting, NeurIPS, plus CEO speaking opportunities.
• Performance KPIs: user acquisition, engagement, content reach, inbound pipeline.
• Function building: operate solo for the first 6 months, then help hire the second marketing team member.
